Ahead of their season finales tonight, Syfy has renewed both Ghost Hunters and Paranormal Witness for 13 episodes each.

In Season 11 of Ghost Hunters, TAPS (The Atlantic Paranormal Society) founder Jason Hawes will lead investigations at reportedly haunted locations including the Cleveland, Ohio’s Midwest Railway Preservation Society, believed to be tied to the notorious, unsolved Cleveland Torso Murderer serial killer case; Crown Point, Indiana’s Old Lake County Jail, famed for being home to gangster John Dillinger…until he escaped; and the Toledo Yacht Club in Toledo, Ohio, said to be haunted by a boy who died over a century ago.

The fifth season of Paranormal Witness: True Terror will delve deeper into actual horror stories, while continuing to feature eyewitness accounts of the most frightening and compelling first person accounts of paranormal encounters, alongside dramatic reenactments of those experiences.

Both series will have their current season finales tonight, Wednesday, November 18. At 9PM, Ghost Hunters returns to author Edith Wharton’s home, The Mount in Lenox, Massachusetts, to investigate claims of increased paranormal activity since the team’s last visit in 2008. At 10PM, Paranormal Witness concludes with a terrifying account of a young family that moved into a house plagued by the vengeful spirit of their great aunt.

Paranormal Witness: True Terror is produced by Raw TV (The Imposter, Locked Up Abroad and Gold Rush). Executive Producer is Mark Lewis, Series Producer is Crispin Reece, and Supervising Producer is Simon Mills.
